Pre startup safety reviews

Pre-Startup Safety Review (PSSR) Services

At Apex Process Safety Solutions, we help chemical, petrochemical, and process industry clients ensure that new or modified facilities are safe, compliant, and ready for operation through comprehensive Pre-Startup Safety Reviews (PSSR).

A PSSR is a critical final checkpoint before introducing hazardous chemicals or starting production. It verifies that all safety systems, procedures, and controls are in place, functional, and understood by operating personnel.

Why PSSR is Important

• Prevents Incidents – Identifies missing safeguards or incomplete work before startup.
• Regulatory Compliance – Required under OSHA Process Safety Management (PSM), OISD Standards, and international best practices.
• Risk Reduction – Ensures design intent, safety measures, and operational readiness are aligned.
• Operational Readiness – Confirms systems are tested, personnel are trained, and documentation is complete.

When PSSR is Required

A PSSR should be conducted:

• Before starting up a new facility or process unit
• After major plant modifications under the Management of Change (MOC) process
• After extended shutdowns where safety-critical systems may have degraded
